Well, I kept thinkin’ I was “smellin’ some wet” for a week or so. We’d climbed under the house and begun leveling it a little at a time for the last few weeks. (tryin’ to get it done while it’s still too chilly for snakes under there) I’d noticed this one water line was touching the ground and looked rusted and worn, went under today and heard it even before I got my head through the underpinning. Fortunately it was a very accessible pipe and was more time consuming than trouble.
I think mine is a drain line, all the water lines are new! ;)
